This document presents lidar-derived elevation data for Maynard Mountain in Southcentral Alaska. The data, collected on July 29, 2022, includes a classified point cloud, digital surface model, digital terrain model, and intensity model. The purpose of the survey was to assess landslide hazards, and the data can be downloaded from the Alaska Division of Geological & Geophysical Surveys website. The document also provides information on the mission plan, processing report, survey details, and acknowledgments. It includes raw data for elevation measurements taken at various points, including coordinates and measurements from ground control points (GCP) and the corresponding point cloud measurements. The document also presents statistics such as average elevation differences, minimum and maximum differences, average magnitude error, root mean square error, and standard deviation for the measurements. Additionally, data for check points, including coordinates, checkpoint elevation measurements, corrected point cloud measurements, elevation differences, and standard deviation, are included.

The Alaska Division of Geological & Geophysical Surveys conducted an aerial lidar survey of Wrangell Island in Southeast Alaska to produce elevation data following a debris flow that occurred on November 20, 2023. The survey collected snow-free surface elevations for landslide hazard assessment. The lidar data was collected using a Riegl VUX1-LR22 laser scanner integrated with a global navigation satellite system and an inertial measurement unit. The survey area covered approximately 40.1 km2 and the data is available for download on the DGGS website. [Extracted from the article]

The article discusses federal role in research, assessment, and response related to landslides. Topics include U.S. Geological Survey (USGS) Landslide Hazards Program (LHP), landslides triggered by rainfall, particularly rainfall on burned, steeply sloped terrain, earthquake, and federal agencies involved in landslide science and applications including the National Science Foundation (NSF).

The Annual Report from the Alaska Division of Geological & Geophysical Surveys provides an overview of the Hydrology & Surficial Geology Section's programs and projects. These programs focus on hydrology, surficial geology, and lidar data collection and processing. The section collaborates with other scientists and organizations to enhance understanding of geologic hazards such as landslides and coastal erosion. The report also highlights the Hydrology Program's work on water-related projects, including permafrost degradation and road construction, and the Surficial Geology Program's mapping efforts, particularly in the North Slope region as part of the Arctic Strategic Transportation and Resources (ASTAR) project.

The Annual Report from the Alaska Division of Geological & Geophysical Surveys provides information on the Geologic Hazards Section, which focuses on studying and responding to geologic processes that pose threats to lives and infrastructure in Alaska. The report discusses various programs and initiatives undertaken by the division, including assessing avalanche, earthquake, tsunami, and landslide hazards. The division collaborates with other organizations and uses data, modeling techniques, and mapping to improve preparedness, resilience, and public education regarding these natural hazards. The programs aim to provide accurate information and support decision-making for communities in Alaska. [Extracted from the article]

The article focuses on laws governing landslide hazards under the 116th U.S. Congress. Topics discussed include national landslide hazards reduction program within the U.S. Geological Survey; introduction of National Landslide Preparedness Act in the Congress; and the take of Department of the Interior on the same.

The article discusses the findings of a geologic and geotechnical evaluation of a landslide at the Yukon River bridge, conducted by State of Alaska's Division of Geological & Geophysical Surveys. Topics include the regional geology and geomorphology of the Yukon River bridge vicinity, the Yukon River Bridge landslide field review performed August 25-29, 2013, and the results of rock mass and discontinuity evaluation.

The article focuses on the development of landmass in England for which four teams working in collaboration to carry out integrated programme for determining the geochemical and physical properties of landmass. The programme helps in the sustainable development of cities and environmental health. Three-dimensional (3D) visualisation and stereo air photography techniques helped improve both survey efficiency and accuracy for landslides investigation.
